Power Supply
This watch is equipped with a solar cell and a rechargeable battery that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face is | Solar cell |
pointing at a light source. |
|
•The illustration shows how to position a watch with a resin band.
•Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.
•You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.
Important!
•Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Be sure that the watch is exposed to bright light whenever possible.
•This watch uses a rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.
•Never try to remove or replace the watch’s rechargeable battery yourself. Use of the wrong type of battery can damage the watch.
•All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
•Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

•The flashing L indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.
•The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5.
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher
than the actual battery level. The correct battery level should be indicated after a few |

minutes. | 3 |
